Wilk Coefficient Applied

The Wilks Coefficient Applied calculator computes Wilks Coefficient formula value and applies it to Good Lift weight.

INSTRUCTIONS: Choose units and enter the following:

• (w) Weight Lifted
• (x) Weigh of Person
• (g) Gender of Person

Wilks Coefficient Adjusted Weight (WCAW): The calculator returns the adjusted weight in kilograms.  However, this can be automatically converted to other weight units (e.g. pounds) via the pull-down menu.

The Math / Science

The formula for the Wilk's Coefficient applied to a weight lifted is:

    `WCAW = 500/ (a+bx+cx^2+dx^3+ex^4+fx^5) * w`

where:

• WCAW = Wilks Coefficient Adjusted Weight
• x = body weight of the lifter
• w = weight lifted by the weight lifter
• a,b,c,d,e,f = f(gender)

For men:

a = −216.0475144
b = 16.2606339
c = −0.002388645
d = −0.00113732
e = 7.01863E−06
f = −1.291E−08

For women:

a = 594.31747775582
b = −27.23842536447
c = 0.82112226871
d = −0.00930733913
e = 4.731582E−05
f = −9.054E−08
